Evaluation of Pr2Zr2−xCexO7±δ pyrochlores as a potential Cu support catalysts for CO oxidation in simulated GDI conditions
Elsevier (2023-03)This study evaluates the catalytic activity, both as bulk catalysts and as supports for copper catalysts for CO oxidation in a simulated Gasoline Direct Injection Engine (GDI) of two pyrochlores: Pr2Zr2O7 (PZ) and ... -
Fotocatalizadores Bactericidas de Perovskita Hexagonal Sr4Mn2CuO4 Para La Degradación De Lixiviados Resistentes A Tratamientos Convencionales
Comité del Congrés (2021)Photocatalytic oxidation processes have been considered to be one of the promising methods applied for leachate from landfills. Azo dyes that contain the -N = N- group are widely used as colorants in the textile, paper, ... -
Insight into Copper-Based Catalysts: Microwave-Assisted Morphosynthesis, In Situ Reduction Studies, and Dehydrogenation of Ethanol
Wiley (2011)Copper-based catalysts obtained by microwave-assisted morphosynthesis were correlated with the dehydrogenation of ethanol. The degree of reduction was monitored using time-resolved in situ XANES during TPR under H2. A ... -
Insight into the antibacterial mechanism of Cu-enriched sol–gel coatings employing proteomics
Royal Society of Chemistry (2023)Advanced antibacterial biomaterials can help reduce the severe consequences of infections. Using copper compounds is an excellent option to achieve this goal; they offer a combination of regenerative and antimicrobial ... -
Investigation of the Hydroxylation Mechanism of Noncoupled Copper Oxygenases by Ab Initio Molecular Dynamics Simulations
Wiley (2013-11-20)In Nature, the family of copper monooxygenases comprised of peptidylglycine α-hydroxylating monooxygenase (PHM), dopamine β-monooxygenase (DβM), and tyramine β-monooxygenase (TβM) is known to perform dioxygen-dependent ... -
Oro y bronce en el yacimiento de Santa Llúcia (Alcalà de Xivert-Alcossebre, Castellón). Reflexiones sobre la actividad metalúrgica en los asentamientos del Hierro Antiguo del Levante peninsular
Servei d’Investigacions Arqueològiques i Prehistòriques (2020)Las excavaciones llevadas a cabo en el asentamiento de Santa Llúcia desde el año 2012 han recuperado diferentes hallazgos metálicos de base cobre y plomo que indican la presencia de un pequeño taller metalúrgico durante ... -
Single and Combined Associations of Plasma and Urine Essential Trace Elements (Zn, Cu, Se, and Mn) with Cardiovascular Risk Factors in a Mediterranean Population
(2022-10)Trace elements are micronutrients that are required in very small quantities through diet but are crucial for the prevention of acute and chronic diseases. Despite the fact that initial studies demonstrated inverse ... -
Theoretical Exploration of the Oxidative Properties of a [(trenMe1)CuO2]+ Adduct Relevant to Copper Monooxygenase Enzymes: Insights into Competitive Dehydrogenation versus Hydroxylation Reaction Pathways
Wiley (2008-07)Singlet and triplet H-transfer reaction paths from CH and NH bonds were examined by means of DFT and spin-flip TD-DFT computations on the [(trenMe1)CuO2]+ adduct. The singlet energy surfaces allow its evolution towards ... -
Unprecedented Solvent-Assisted Reactivity of Hydrido W3CuS4 Cubane Clusters: The Non-Innocent Behaviour of the Cluster-Core Unit
Wiley (2009)Opening the cluster core: Substitution of the chloride ligand in the novel cationic cluster [W3CuS4H3Cl(dmpe)3]+ (see figure; dmpe=1,2-bis(dimethylphosphino)ethane) by acetonitrile is promoted by water addition. Kinetic ...
